Claims

[Scope of utility model registration request]

A bushing rod that connects the printing hammer and actuator and transmits the driving force of the actuator to the printing hammer, and two guide plates that are made of synthetic resin with a large coefficient of thermal expansion and support the bushing rod in a slidable manner. and a backup plate made of a metal material such as iron having a small coefficient of thermal expansion and fixed to at least one side of the guide plate to reinforce the guide plate, the bush rod guide assembly comprising: and a positioning member that passes through the backup plate, and a spring that presses the guide plate and the backup plate through the positioning member, and the hole in both guide plates that the positioning member passes through is a long hole that extends in the length direction of the bushing rod. A butsch rod guide assembly characterized in that it is formed as follows.
